Organize your data as below. Note that you have to use a date together
with the time (you are crossing midnight after all)

Name Start Duration
MC1 1/1/2005 23:45 01:43
MC2 1/1/2005 23:55 01:32
MC3 1/2/2005 00:05 00:23

Now, create what XL calls a bar chart (horizontal bars) and for the
subtype select 'stacked bar' (step 1 of the wizard). Ensure that in
step 2 of the wizard XL has data in columns selected.

Once done, double-click the first plotted series and from the Patterns
tab set both the Border and Area to none.
